Multi-speed setting
(speed 8)
By setting any value other than "9999", set speeds 8 to 15.
This function is designed to change the running speed in stages by changing the ON/
OFF combination of the contact signals (RH, RM, RL, REX signals).

Sub functions
240 Soft-PWM setting
You can select to exercise Soft-PWM control and long wiring mode. When Soft-PWM
control is made valid, you can change the metallic tone of motor sound into an
unoffending complex tone. Surge voltage is surpressed in the long wiring mode
regardless of the wiring length between the inverter and motor. (When operating a
400V motor with wiring length of 40m or more, select long wiring mode.)
0: Soft-PWM control invalid, long wiring mode invalid
1: Soft-PWM control valid (when Pr. 72 = "1 or 2"), long wiring mode invalid
10: Soft-PWM control invalid, long wiring mode valid (carrier frequency is 2.25Hz *)
11: Soft-PWM control valid, long wiring mode valid (carrier frequency is 2.25Hz *)
*The Pr.72 "PWM frequency selection" setting is made invalid.

Cooling fan operation
selection
You can control the operation of the cooling fan built in the inverter.
0: The fan is always operated at power-on of the inverter.
1: The fan is always on while the inverter is running. During a stop, the inverter status is
monitored and the fan switches on-off according to the temperature.

Stop selection
function
250 Stop selection
Set to allow the motor to be coasted to a stop by turning off the start command during
V/F or speed control.

Output phase failure
protection selection
You can disable the output phase failure function that stops the inverter output if one of
the inverter output side (load side) three phases (U, V, W) opens.
0: Without output phase failure protection
1: With output phase failure protection
